Transcribed Image Text:The graph below shows a "snapshot" of a sinusoidal wave in a string. A formula for the power of this
wave (the rate at which it transports energy) is given below the graph. To use this formula, estimate from
the graph the amplitude of the wave to the nearest tenth of a centimeter.

u = linear mass density
w = angular frequency
A = amplitude
v = speed of wave
Suppose u = 0.016 kg/m, w = 440_Hz, and v = 8.7 m/s. Then calculate the power of the wave.
